Here’s the simple way to use Roblox web audio for the MM2 radio : buy/equip the radio game pass in Murder Mystery 2, find a Roblox audio you’re allowed to use, copy its numeric ID, then paste that ID into the radio’s sound box and hit play.

Quick Scoop

  1. Open Roblox on the web and go to the audio/creator marketplace area to search for a song.
  1. Copy the audio’s ID number from the URL or item page.
  1. In MM2 , equip your radio from inventory, open the radio menu, and paste the ID into Enter Sound ID or the song field.
  1. Press Add or Play to save it to your song list and start using it in-game.

What to know

  • The radio is a paid item/game pass, commonly listed around 475 Robux in current guides and the wiki.
  • Radios are used during rounds, but not in Hardcore mode.
  • Some search features in the radio menu can be unreliable, so pasting the ID directly is the most common method.

Common setup

Open inventory → radios → equip one → click the radio icon in-game → paste the sound ID → add/play.

If a song does not work, it may be because the audio is no longer available or Roblox changed access rules for some sounds.

TL;DR

Buy/equip MM2 radio, get a Roblox audio ID, paste it into the radio menu, and hit play.
